The present invention relates, generically, to composite woodensurfaces, such as wall panelling, flooring (strip, parquet, etc.) andthelike. More particularly, this invention type of composite wooden surfacewhich is adapted to be laid on underfloorings or back ings of concreteand similar material.

It is a common; experience in the flooring tradeto findthat in stripflooring laid upon 7 concrete underflooring there is a marked tend ency,for the strips to separate from each other and to leave relativelylargeand unsightly crevices therebetween. This has been partially overcome bythe use of an intermediate layer of :wood between the'concrete backingmember and the surface flooring, the latter being nailed or otherwise"securedto theintermediate layer. The use'of the intermedi- 1 Theprimary object of the present nvention to provideafastener for thestrips or component members '(such as unitsof-paracter abovedescribedwhich maybeeasilyand? n p n ve f m in. dies ut stri' a tal' "asof -a;single f; f

e athei e 7 Side,

". a v I of vertical pontions 18 The ye gtieal portions 18 are adaptedto be received in the space left between shortened tongues 14 ofadjacent strips of flooring, as

- is clearly shown in Figs. 1 and 2.

Base portions 17 are formed with longitudinally extending beads 19intermediate the sides thereof and ate. point thereon beyond thecorresponding tongue 16. When these beads 19. are ultimately flattenedout, as and for the purpose hereinafter described, the

base portions 17 aresubstantially coextensive with and adapted to bereceived in the rabbeted grooves 13. The base portions 17 extend onlyfrom one side of the vertical members 18, and with the correspondingtongues 16 form sockets adapted to receive the tongues 14 of adjacentflooring strips. The tongues 16, vertical portions 18 and bases 17 ofthe fasteners 11 are continuous and longitudinally coextensive with eachother.

The fasteners 11 may be cut into conven ient lengths and cooperate withflooring strips, as shown, to provide a firm support therefor along theentire length thereof.

' At the crests thereof, beads or raised portions 19 are formed with aplurality of spaced nail-receiving holes or openings 20. Substantiallymidway between these openings 20,

I thebeads may be and preferably 'are provided with suitably shapedslits or cut-outs In; describing the method of laying a floor accordingto the present invention, particular reference will be had to Figsil and2 of underflooring 15 is preferably first coated with-a layer of masticor similar material.

-As.shown' in Fig. 1, strip 10a has'already.

beenlaidand its fastener 11a secured in place on the underflooring bymeans of nails or other fastening elements 22. This leaves one tonguelfiand the flattened base 17 exposed, the other tongue 16 being received ina groove 12 of the'strip 10a. A second strip of flooring 10b is then putin place, a groove 12 thereof receiving the said exposed tongue 16,and arabbet 13 receiving the flattened base 17. It has been found byexperience that the 'several strips cannot ordinarily be laidso;that

they will contact along the entire adjacent sides thereof, but thatthere is always a slight space therebetween, as shown at 23iuF-i'g. 1.'The tongue 16 of a second fastener 11b is then inserted into theexposedgroo've. vI2 of the strip 106 with base portion 17 oflthefastener 11?) extending outwardly. Nails 22 said base portionintermediate'the sid are then driven into the concrete sub-flooring 15through openings in the beads 19. This flattens the bead out andincreases the effective width of the base 17. To accommodate thisincrease in width, the strip 10b is forced over to the left (in Fig. 1)into intimate contact with the strip 10a, thus eliminating the openingor crevice 23. Since the nails 22 penetrate into the concrete before theflattening of the beads begins, they, of course, do not give, andseparation of adjacent strips to form spaces therebetween is positivelyprevented. This process is continued with additional strips andfasteners until the entire floor is laid. The slits or cut-outs 21 areadapted to receive superfluous mastic from the surface of themastic-covered sub-flooring, thus aiding in securely holding thefasteners down on the latter.

It will be thus seen that a simple and efficient fastener has beenprovided for use with flooring designed to be laid upon concreteunder-floors. It is obvious that the improved fastener may be equallywell used with properly milled units of parquetry in the laying ofparquet flooring, and also in the laying of the panels of composite wallsurfaces.

In accordance with the patent statutes I have described the principlesand particu ar have illustrated and described a particular formation, Idesire to have it understood that the same is only illustrative of ameans of carrying out my invention in one form and that obvious changesmay be made by anyone skilled in the art within the scope of thefollowing claims without departing! from the spirit of my invention.

I claim: a

1. In a fastener for flooring and the like a base portion extendinglaterally from the body of the fastener, and a nail recei raised portionextending longitudinall o y t ereof, said raised portion being adaptedto be flattened when nails are driven therethrough into the flooring orthe like.

2. A device of the class described comprising a vertical body portion, apair 'of tongues extending laterally in opposite directlons from the topof said body portion, a base portion extending laterally from said bodyportion at the bottom thereof, saidbasef portion having a bead extendinglongitudinally thereof and adapted tobe flattened.

3. A fastener for flooring and: the like adapted to bemade'from a singlestripoffsheet metal comprising a vertical member; a pair v mi r oftwo-ply tongues at the top of said-vertical member, abase'portion at thebotton'i; of said vertical member, a raised bead extendinglongitudinally of"*said base portion, said; head having a plurality ofnail-receiving openings at the crest; thereof. 4. In combination with astrip of flooring disposed upon a sub-flooring, a fastener for saidstrip of flooring, means to anchor said fastener to said sub-flooring,and raised means on said fastener adapted when flattened to force saidstrip into intimate contact with the next adjacent strip of flooring.

1 5. The method of laying flooring upon concrete sub-flooring comprisingdisposing a fastener adjacent a strip of flooring, anchoring saidfastener to said sub-flooring, and then increasing the eflective widthof said fastener,

whereby said strip of flooring is forced into I intimate contact withthe next adjacent strip of flooring.

6. A fastening'device comprising a base portion, a vertical portionattached thereto, 7 2 a plurality of tongues extending laterally fromsaid vertical portion, said base portion and vertical portion beinglongitudinally coextensive and continuous, and raised means on said baseportion adapted, when flattened, to increase the effective width of saidbase portion.
